Shimano Ultegra CN-6800 11-speed Chain

Stronger, slimmer, and lighter? How did Shimano make the new Ultegra 6800 11-speed chain with less material, to slip smoothly over more gears, and able to take more torque, more cross-chaining, and more all-around abuse? Partially because of forging technology, and partially using new PTFE coating on the links, designers were able to make links almost .5mm slimmer and 20% stronger. As with the rest of us, slimmer means lighter. Wow up your drivetrain with 253g of race-ready chain....
